That’s what it’s come down to on the CBS series “Person Of Interest,” it’s time to put up or shut up for “The Machine” and her human operatives. Artificial Intelligence system Samaritan’s on the offensive, seeking to find “The Machine’s” location, destroying the life of a software pioneer in the process. Samaritan’s administrator John Greer’s seen his wishes fulfilled, Samaritan’s a system without a moral code, willing to do what ever takes to get the mission accomplished. The only thing standing between it and global domination’s, Harold Finch’s creation and the strength of John Reese. What they found out in this episode however, was they can’t save a man who wants to find out the truth, despite the costs.

Sulaiman Kahn, founded Castellum Security Inc. in his garage, he starts out the episode of the CEO of the planet’s largest manufacturer, of anti-virus software. However, Samaritan hijacked his company out from under his nose. He wakes up to find his picture on every network, newspaper and information website, as all his private information got leaked by a hacker. The released documents also show that he’d been embezzling company funds and that he has outstanding warrants for arrest in six states. All of that information, got planted into his files by Samaritan.

Kahn’s also the latest number given to Finch and Reese, they watch as piece by piece, Kahn’s life’s torn apart. Fired and escorted from his business, by his own security guards, he gets a call from his wife Linda, saying she’s humiliated as photos of him with other women in the Middle-East have gone viral.

Reese follows Kahn to a neighborhood bar, where Kahn meets his associate and longtime friend Mark Lee. He tells Lee that he’s gotten targeted by an Artificial Intelligence System and he needs Lee to check the power meters in the company’s building. Mark replies that either Kahn’s insane, or correct, either way he wants to get away from him, but Kahn swipes Lee’s swipe-card to enter the building.

John follows Kahn into the building, watching as the CEO removes a fastened metal screen, obstructing the meters. He gets to the meters, when Finch tells Reese that the NYPD is on the way and John’s cover identity Detective John Reilly, shouldn’t be seen there. Samaritan will surely discover him, putting everyone in danger, he watches from the shadows as he’s arrested.

Fusco finds out they sent Kahn to Riker’s Island, he and Reese go there to get him released, but the officer at the desk says Kahn’s being held on warrants from six states. Samaritan contacts one of Kahn’s fellow inmates, offers him 100 thousand to kill Kahn, then disables the video-cam feeds. Kahn’s getting strangled, when Reese dressed as a prison guard, takes out the attackers and pulls Kahn out to freedom.

Reese has a NYPD SUV, and drives away from Riker’s, going through red lights, to escape their pursuers. However, Samaritan activates the Street Bollards, which are like six-inch little poles, emanating from the asphalt. Reese hits the poles and the SUV flips over, Kahn’s knocked out, but John climbs out, aiming a pistol at an oncoming vehicle. Root’s driving and asks if John wants a ride?

Finch, Root and Reese, eating Chinese Take-Out while Kahn’s still passed out in a chair, his head on the table. Root asks if Harold’s forgiven her, he says we have other pressing matters, as long as he’s here, this safe-house, won’t be safe for long. Root asks how can you hide, when a God wants to find you, then says we should blow his mind and tell him there’s two of them.

Kahn wakens, sees the three of them and tries to flee, unaware there are manacles on his feet. He asks who they are and Reese responds, they’re the folks keeping him alive. Harold says that if he answers their questions they’ll release him, while Reese puts him back in his chair. Reese asks why he wanted to see the meters so badly, Kahn responds that they registered using ten times more power, than his company ever utilized. He says that’s powering an outside system, Then he says that an Artificial Intelligence System’s destroying his life, he believes the reason’s for his research, he’s about to get into biotech manufacturing. A digital immunization chip, that he believes the system wants to make a prototype of without him.

Root’s able to locate an IP address of the facility that’s siphoning off the power, Kahn insists on going with them. She picks up signals from video cameras in the wooded area they arrive at, which John destroys with some quick shooting. They find a set of metal doors that lead to an underground facility in use. John and Root takeout the terminal operator, but Harold gets alarmed at the code he sees on the screen, Root does as well as she says they need to leave.

Martine Rousseau and a squad of Samaritan assassins are on scene when they emerge, a shoot out engages as John and Root take out a bunch of operatives. Root then goes for Martine, they’re both out of bullets, so they start walloping each other, Root’s nearly choked the life out of Martine, when Reese pulls her off the Samaritan operative. He later says he should have let Root kill her. Kahn runs away in the confusion.

However we find out his fate in the episode’s final scene, when he’s presented to Greer and Rousseau. Greer tells him that Samaritan did hijack his company, but for different purposes than he suspected. Samaritan used the software to find “The Machine.” Khan says he wants to see Samaritan, wants to look it in the eye, Greer says alright then and shoots Kahn in the chest, he dies instantly.
